Get running VMs on Azure - azure

Question

I have the below code to check daily if all the VMs that are meant to auto-start have started successfully.
$Date = (Get-Date -Format "dd-MM-yyyy HH-mm").toString()
$Results = "C:\temp\DailyChecks_$($Date).txt"
$Cred = get-credential -UserName 'AZ-User'
Connect-AzAccount -Tenant 'TenantID' -credential $Cred | out-null
$fCount = (Get-AzVM -Status | Where-Object { $_.tags['Managed By'] -like 'Manager' }).count
do {
$rCount = (Get-AzVM -Status | Where-Object { $_.tags['Managed By'] -like 'Manager' -and $_.PowerState -eq 'VM Running' }).count
if($rCount -lt $fCount)
{
write-host "There are $rCount VMs running, checking again"
}
elseif($rCount -eq $fCount){write-host "There are $rCount VMs running, exiting loop"}
}until($fCount -eq $rCount)
Get-AzVM -Status | Where-Object { $_.tags['Managed By'] -like 'Manager' } |
Select-Object Name, PowerState | Format-Table | out-file $Results
I have a couple of questions:
Is there a better way to write this code?
How can I check if the code has been running for longer than 30 minutes and yet not all VMs are running?

Answer 1

You can determine for how much the time the script is running by using a StopWatch object.
$sw = [System.Diagnostics.Stopwatch]::new()
$sw.Start()
Whenever you want, just check the elapsed time by checking the elapsed property
$sw.Elapsed
$sw.Elapsed.TotalSeconds
Write-Host "Time elapsed: $([Math]::Round($sw.Elapsed.TotalMinutes,0)) min $($sw.Elapsed.Seconds) seconds"
